Thus 5x3 becomes 5x5x5 or 3x3x3x3x3 instead of "STFU and memorize your times tables."

I'm fine with the repeated addition. My objection is the OR in your statement. Apparently not. The question was 5x3 and the kid wrote 5+5+5=15 and got marked wrong with no explanation because the teacher wanted 3+3+3+3+3=15. So I guess that you would have had a 50% chance of being marked wrong on a 2nd grade arithmatic worksheet as well, as absurd as that is. Correct answer notwithstanding.

BTW, that's not at all new. We covered multiplication that way in the 3rd grade back in 1975. Memorizing the table was just to make it quicker. I quickly "discovered" the commutative property while looking at the multiplication table and cut my memorization load in half. The part that confused the father was why is 5x3 = 5+5+5=15 "wrong".

As for 37+55, we decomposed that in the '70s as well, but I soon decided the easier decomposition was 37+55= 87+5 = 90+2=92. So I would say that meme was just someone wanting to complain. Of course the "old way" ends up in 30+50+10+2 anyway.

Shut up and memorize was not in practice during the education of the parents of today's students.

OS/2 had no security features needed for multiuser support. It might as well have been classic MacOS. Citrix had a multiuser version of OS/2 with security tacked on, but it wasn't a realistic solution and was never popular. Building an OS without security was the moronic decision that killed it. Plus IBM never did anything meaningful to promote it so nobody cared. That it was used anywhere (especially in ATMs) was a horrible decision itself because of the lack of security features and has created untold woes. Maybe nobody ever got fired because they bought IBM, but they should have.

It is neither right or wrong

It's wrong. The processor has a feature. People will reasonably assume they can use that feature. Then they find out it's disabled.

assuming the features or lack thereof is declared upfront.

If that declaration is not in the largest font size used in the materials then it's hidden.
